To install new font on your linux server run by CentOS, if we are talking about Google fonts, you have to make these steps:

1. go to Google fonts and download your font folder:

here we will download font that support Japanese characters

2. extract your font and upload complete  "static" folder from unpacked font file 

3. Renema that folder to font name, on our case we will rename to NotoSansSC

4, copy that complete folder to your server folder path /usr/share/fonts/:

                    sudo cp -r /path/tp/your/folder/NotoSansSC /usr/share/fonts/

5. clear font cache

                    sudo fc-cache -f -v

6. list your fonts, and your new font should be there:


.... and boom! that is it! 
you have your new font installed.
